I just released the version 0.4 of the django-meio-easytags. I added a subclass of django’s default template tags Library. And now it’s easier to create a template tag. Take a look.

I just released a project I have been working today. A long time ago, I was tired of parsing my template tags by hand, then I created a BaseNode to do this work for me and all I had to do was subclass it and define the method to render the context.
Last friday, my friend Diego Fleury asked me for some help developing a template tag and I talked to him about my old BaseNode. When I showed the code to him, he didn’t understand it so did I. So I wanted to make it cleaner and developed the project django-meio-easytags. It’s hosted at Github (http://github.com/vbmendes/django-meio-easytags/).
It’s very easy to create your own template tags with it. Take a look: https://github.com/vbmendes/django-meio-easytags/blob/master/README
Any comments and contributions are welcome.

I will talk about a shortcut I developed for the Django framework and always use in my apps. This code is aimed in making a quik shortcut to obtain the first object of a queryset if it exists or
It’s very useful when you want to display the last news in the first page of your website, but don’t want it to break if there isn’t one to show. It’s just a use case for such a code, but there are many more.
In the past I used to write something like this:
try: first_user = User.objects.all()[:1] except IndexError: first_user = None
This is four lines to do a very simple task and I wanted to evolve this to use only one line of code. So I developed a function that do this to me. It’s inspired in the
django.shortcuts.get_object_or_404. Let’s take a look at the code:
def get_first_object_or_none(queryset): try: return queryset[:1] except IndexError: return None
I’ve put this code in a module called
shortcuts inside my project and now everytime I want to use it I can write this code:
from shortcuts import get_first_object_or_none first_user = get_first_object_or_none(User.objects.all())
I think it’s a very good result and helps a lot in my coding. It also made my code more legible and easy to understand. It increased my productivity and I am publishing to increase others productivity also. Any doubts, questions os suggestions, please leave a comment.
